Alternate wiring (heat pump system only)
Leave metal jumper in place, connecting R & Rc terminals.
If your old thermostat had both V and VR wires, stop now and contact a
qualified contractor for help.
If your old thermostat had separate O and B wires, attach the B wire to
the C terminal. If another wire is attached to the C terminal, stop now
and contact a qualified contractor for help.
If your old thermostat had Y1, W1 and W2 wires, stop now and contact
a qualified contractor for help.
If L terminal is used, C terminal wire must be connected (contact a
contractor if there is no C wire).
If E and Aux terminals do not each have a wire connected, use a small
piece of wire to connect them to each other.
Use the Setup and Navigation steps in 12a to set Display Preferences.

1 Press s t to change setting.
2 Press NEXT to advance to next function.
3 Press DONE to save & exit.
Alternate wiring (conventional systems)
Remove metal jumper connecting R and Rc only if
you must connect both R and Rc wires.
If your old thermostat had both R and RH wires,
remove metal jumper. Connect the R wire to the
Rc terminal, and the RH wire to the R terminal.
If your old thermostat had only 1 C or C1 wire,
connect it to the C terminal. If your old thermostat
had 2 C or C1 wires, wrap each separately with
electrical tape and do not connect them.
